Bruce M. Chassy

Professor Emeritus of Food Safety and Nutritional Sciences, Department of Food Science and Human Nutrition, University of Illinois at Urbana-Champaign

Bruce M. Chassy is a Professor Emeritus of Food Safety and Nutritional Sciences from the Department of Food Science and Human Nutrition at the University of Illinois at Urbana-Champaign.  He served as the Assistant Dean for Science Communications in the College of Agricultural, Consumer and Environmental Sciences and was Head of the Department of Food Science and Human Nutrition at the University of Illinois from 1989 to 2000.  Dr. Chassy completed his undergraduate training in Chemistry at San Diego State University and his Ph.D. in Biochemistry at Cornell University.  He was a research chemist at the National Institutes for Health (NIH) from 1968-1989.  Dr. Chassy was a Fulbright Distinguished Lecturer in Spain in 1994.

Dr. Chassy’s research focused on the characterization and development of methods for the genetic manipulation of microorganisms used in food and dairy fermentations.  His research experiences with the development of genetically modified microorganisms that are used in foods led him to an interest in food safety and the safety evaluation of "biotech foods.” He maintains a website that explores the safety of GM foods at http://academicsreview.org.

A: No! There is no way to detect whether an animal has been fed GM feed because there is no content from any part of the GM feed in the flesh, milk or eggs.  The GM feed is digested and assimilated in exactly the same way as any other feed.  There is in fact no meaningful measurable difference between GM and convention feeds. Actually that's not exactly true.  It turns out that conventional and organic feeds can have more of the mycotoxin fumonisin in them than does insect...

A: It is good that the questioner recognizes the importance of relying on the testimony of experts when trying to understand complex scientific issues. Jeff Smith is, however, not a doctor or researcher and he has never conducted a scientific study or published a peer-reviewed scientific paper.  Please read his Biography at his website (http://www.responsibletechnology.org/resources/media-kit/jeffrey-m-smith-bio) to confirm this.  He is an energetic, articulate and persuasive...

A: The composition of GM crops and foods derived from them is carefully studied.  Using our knowledge of toxicology, food allergy, and nutrition, it is possible to predict if a food will have an adverse effect based on composition alone.  The study of composition is a better indicator of safety than are animal studies on whole foods.  Many scientists in fact question if whole food studies in animals are useful and have suggested they not been done.  Studies in humans are even...

A: This is a very interesting question to which we would like to add one additional factor. Evolution and adaptation can be one response to change; extinction can be another. As highly evolved beings we are fortunate that we are not among the greater than 99% of all species that have gone extinct!  The plants that we farm descended from wild plant ancestors but they were extensively genetically modified over the years by a process called domestication.  The ancestor of modern corn, for...

A: I understand that claims made by Jeffrey Smith, the movie’s director and author the self-published book, Genetic Roulette, are alarming and could cause great concern. It’s important to understand Mr. Smith’s background. He is not a doctor or researcher and he has never conducted a scientific study or published a peer-reviewed scientific paper. Please read his Biography at his website (http://www.responsibletechnology.org/resources/media-kit/jeffrey-m-smith-bio) to confirm this. He is an... Continue Reading
